It's a war of Kates — or Cates — as the search for Robin Hood’s Maid Marian continues.

I told you the other day about Sienna Miller leaving "Nottingham," the Ridley Scott directed feature set to star Russell Crowe. The feeling was that petite, young Miller would seem dwarfed on screen by the older, beefier, "Gladiator" star.

Now comes word from sources that Kate Winslet, nominated for Best Actress in "The Reader," has passed on the role of Maid Marian and the opportunity to spend quality time with Crowe, Scott and pals in the woods.

A new offer has just gone out to Cate Blanchett, I am told, but the answer is likely to come back negative. Blanchett is likely too expensive and too serious to get involved in this venture. An Oscar winner herself for The Aviator in the Best Supporting Actress category, Blanchett also has to set her sight her sights on a Best Actress win. Plus, she already did her action thing with the recent "Indiana Jones and the Kingdom of the Crystal Skull."

Producers are mulling a back up plan, I’m told, waiting to make an offer to Rachel Weisz. This seems almost perfect, as Weisz may be the right price and just at the right point in her career to have "Nottingham" make a difference in upping her profile. And if she doesn’t take it, my suggestion to the producers is Jennifer Ehle. But no one asked me!

It seems like things are pretty shaky these days over at NBC’s "Law & Order: Criminal Intent."

The problem: recently appointed producer Robert Nathan, who was brought in to run the episodes featuring newcomer Jeff Goldblum, is out after shooting two chapters. There’s word that Ed Zuckerman, producer of the original "Law & Order," is taking his place.

But things are not that simple. According to sources, Goldblum’s character has not really emerged yet on screen. "The two episodes they have are terrible," says an insider who says that everyone who worked with Nathan is gone as well.

The result is that USA Studios, which airs the show before it goes to NBC, has postponed the season premiere for a second time. The original prrmiere was set for last November, then moved to March. Now it might be in the late spring or early summer.

The irony is that the eight episodes featuring Vincent D’Onofrio are moving along pretty well, and should be finished on time. The hold up is all with the eight starring Goldblum. They simply don’t exist so far.

Meantime, "Law & Order" executive producer Dick Wolf is also the man behind the new documentary shown last week at Sundance about the rock group, The Doors.

"When You’re Strange" is director Tom DiCillo’s first doc after six fiction features, and he’s done a great job pulling together lots of previously unseen footage of Jim Morrison. In fact, DiCillo is the first filmmaker ever to make Morrison seem like a real person who was very insecure, troubled, and haunted by, of course, parents who didn’t understand him. DiCillo even got his hands on rare footage of a film Morrison was shooting in the desert but never completed.

The film is one of the few that offers anything new or revelatory on the pre-digested Doors myth, and should garner a nice sized audience when it’s finally released. What it doesn’t address is how the three remaining Doors — John Densmore, Ray Manzarek, and songwriter Robby Krieger — have soldiered on since Morrison’s death in a Paris bathtub 1971. It hasn’t been easy. This was borne out by the fact that Densmore refused to sit with Manzarek and Krieger at last week’s screening. Indeed, the trio didn’t even take questions from the audience. They let Di Cillo handle all that.

The debut of the new season of "Lost" was pretty much a ratings nightmare. ABC says it was off by 25% from the last season opener.

I don’t doubt it. Even though the show’s creators claimed in an hour long special that this year "Lost" would answer more questions, it really didn’t. I felt Lost myself, which isn’t good.

The idea of this season is time travel. Okay, but it doesn’t really make sense. Also, the series has abandoned the flashbacks to stories of the characters’ lives, and even the flash forwards. If the characters seem confused, what are the viewers to do?

I do think the biggest problem, though, is that Jack — Matthew Fox — is no longer the show’s sturdy hero and tentpole character. He’s now bearded, taking pills and drinking, and deferring to Michael Emerson’s Ben Linus. This is a big mistake. A multi layered show like "Lost" needs some clearly delineated saints to play off the sinners. Jack has lost his halo, and left the viewers in the lurch.

The best part of the season opener was when Hurley tried recapping everything that happened to his mother. When he got to the part when, early in the show, someone had to press a button every 108 minutes, he shrugged and said something like, "They never really explained that."

Indeed, it turns out that most of the intriguing stuff from the original set up has been Lost, or swept aside without explanation. At this point, there’s no way everything could fit together. I do love Beatle-named Desmond and Penny, though. Until Jack comes back, if ever, they’re the new heart and soul of the show.

Rosie O’Donnell unveils her Maravel Arts Center on Monday with a ribbon cutting in the morning. The center, designed for Rosie’s Broadway Kids, is named for the TV star and comedian’s former teacher Pat Maravel. Located in the heart of the theatre district, the state of the art building includes two dance studios, a music studio, a study café, practice rooms, a library, dressing rooms, administrative offices.
